inverter with UPS charger/12v 220v inverter/3000 watt inverterv:


Product Description

Introduction of UPS inverter:

With a normal input mains power AC220V/AC110V, UPS modified power inverter can transform AC power into DC power so as to power household electronic appliance and equipment , and meanwhile charge the external battery connected with it. when a power failure created the UPS power inverter will immediately transform the DC power of the battery into AC220V/AC110V and simultaneously charge the battery also ,so as to keep equipments and appliances from being damaged.


Product Features:

1) Adopting all-metal aluminum shell, making the inverter safer

2) with charging and UPS automatic switching dual function

3) Independent R&D design, adopting the latest high-frequency PWM technology and big IRF high power transistor imported from USA

4Matched with national, American, European and Australian standard plug

5) With over 90 % conversion efficiency 

6) Protection function: overheat, over voltage, under voltage, overload, over current etc

7) LED indicator showing the work status

8) 100% full power


Technical Specification:

Application of power inverter:

1) In-car or on-boat devices series: Military vehicle, police cars, medical ambulance, 

   ships, traffic lights, and etc. 
2) Industry equipments series: Solar energy, wind power, gas discharge lamp and etc. 
3) Office area: Computer, printer, copier, scanner, digital camera and etc. 
4) Kitchen utensils series: Micro-wave oven, induction cooker, refrigerator, and etc. 
5) House appliance devices: Electric fans, vacuum cleaner, AC, lighting lamps, and etc. 
6) Power tool series: Electric saw, drilling machine, punching machines, air compressors, and etc

Frequncy Asked Questions and Solutions
Q1.The electric appliance doesn't work and the indicator light isn't on.
1. Faulty battery.
2. Wrong connection of positive pole and negative pole.
3. Loose connection of the cables.
1. Check the battery, and change it if needed.
2. Check the connection of battery. The inverter might be damaged and should
be changed or sent to be repaired.
3. Check the cables and connection points, and tighten the terminals.

Q2. The electric appliance doesn't work and the RED indicator light is on.
1. The rated power of electric appliance exceeds the nominal power of inverter
which leads to over load shut down.
2. The rated power of electric appliance is less than the nominal power of the inverter
but its peak power is too high which leads to over load shutdown
3. The electricity in battery runs out (the inverter alarms)
4. Poor ventilation causes over heat shutdown
5. Input voltage is too high.
1. Please use the electric appliance which power is less than the nominal power of inverter.
2. The peak power of electric appliance is no more than that of power inverter, or the same power.
3. Charge the battery or change it.
4. Turn off the inverter for 15 minutes, remove the items near fan and those around the inverter,
and put the inverter in a shady and cool place
5. Turn off the inverter and test the output voltage of battery.

Q3. The output voltage of power inverter tested is too low.
Reason: Generally the numerical reading range of voltmeter for testing use is too small.
Answer: If you test the output voltage of modified sine wave inverters, please use "true RMS?
Muti-meter" to obtain the accurate data.

Q4. Only small power load can be driven.
Reason: When the current goes through the cables, the voltage declines.
Answer: Shorten the length and use thicker cables.

Q5. The hours of use are too short.
1. The electricity consumption of the electric appliance is larger than rated load of power inverter.
2. The battery is faulty or damaged
3. The battery is not well charged
4. The current declines when through cables
1. Use larger capacity battery.
2. Change battery.
3. If the charger can't charge the battery fully, it needs to change a better intelligent charger.
4. Shorten the length of the cables and use the thicker cables.

Q6. How to contact your esteemed company and buy the inverters?
We are in the different regions, but we want to establish the long business with your and your excellent?
